Abstract: One embodiment of the present invention provides a system that can manage access to a service from a cluster of computing nodes. An instance of the system can operate on a respective computing node. During operation, the system instance can identify an Internet Protocol (IP) address, which provides access to the service from the cluster of computing nodes to a client device at a client site. The system instance can select the computing node for hosting the IP address in the cluster of computing nodes based on a set of selection criteria. The selection is performed independently at the computing node. The system instance can then assign the IP address to the computing node. The assignment allows a request for the service to be directed to the computing node. Subsequently, the system instance can facilitate the service from the cluster of computing nodes based on the request.

Abstract: An online system stores online documents, where each online document has a layout. The system creates augmented online documents by combining the online documents with one or more content items. The system stores client interactions with the content items, responsive to presenting the augmented online documents via a client device. The system receives a new online document. The system creates new augmented online documents by combining the new online document with one or more new content items. For each new augmented online document, the system generates a score based on one or more features describing the layout of the new augmented online document. The system selects a new augmented online document based on the generated scores and sends the selected new augmented online document for presentation via a client device.

Abstract: Systems and methods for assessing vehicle operation are provided. According to certain aspects, an electronic device may receive and analyze image data depicting an individual located within a vehicle. The electronic device may also access and compile certain data related to an environment of the vehicle, and specifically to the vehicle's position relative to the sun. According to embodiments, the electronic device may determine, based on the accessed data, whether the vehicle is traveling into a direction of the sun, and may generate and record an indication of the same.

Abstract: Examples of a distributed message service include a virtualized file system including a virtual disk configured to store messages for a message topic, and a broker logically allocated to the message topic. The broker is configured to cause a message directed to the message topic provided from a publisher to be stored at the virtual disk, and to route the message to a subscriber of the message topic that is registered with the broker. The distributed message service further includes an operating system configured to manage the virtualized file system and includes a message service configured to manage logical allocation of the broker and manage allocation of the virtual disk to the message topic.
